Coal flotation cells Engineer Live

Control of product ash in mechanical flotation cells is another important aspect in CHPP operation, with product ash generally increasing down a flotation bank. The primary reason for the increase in ash content down the bank is probably due to the lack of attention to froth stability in coal flotation cell design.
